Patented Feb. 17, 1931 UNITED kSTATES EMILBABER, or Los ANGELES, CALIFORNIA LUBRICATOR Application. filed December This invention relates to devices used for feeding lubricating oil into the combustion chamber of an internal combustion engine Vand therebyl to parts generally not f5 directly lubricated.

One of the objects of thisinvention is to provide a simple device with wick-feed supplying means whereby a certain amount of the lubricant is brought to a certain level in a suitably fine state.

Another object is to provide means whereby air is drawn into and through the wickfeed supplying means so that the wick is maintained in a suitably dry state to con- 15 tinuously draw the lubricant upwardly.

Another object is to provide means to prevent a splashing of the lubricant into the discharge. e

Another object is to provide a comparatively small lubricant drawing tube extending into the wick whereby both, the air as well as the lubricant are compelled to first pass through the wick before passing into the lubricant drawing tube. v

Another object is to provide an attachment to be secured to the top of a lubricant holding container with the wick enclosed tube eX- tending to a point near the bottom of the container.

Another object is to provide means for adjusting the passage through which the lubricant can escape. Y i

Other objects willl appear from the following description and appended claims as well as from the accompanying drawing, in

which- Fig. 1 is a vertical midsectional view of a simple attachment with a wick-feed center tube by which a lubricant is brought close to the lubricant draw tube according to this invention, the attachment being shown in proper relation to the top of a glass jar.

Fig. 2 is a plan view of the underside of the attachment illustrated in Fig; l.

Devices of this type are preferably con-k 5, ,1928i serial` No. 323,918.

which this device is eventually appliedacts 4in the'direction of the arrow 3 so that aflubricant is'drawn through the passage 4; of thejconnection '5 in thedirection of the larrow 6 from the draw-tube7.V The setand ad- 455 Vjusting screw 8 serves fora proper control .tainer 9 is illustrated inform of a Yglass jarO butl it must, of course, be understood that the container may Vbe made of any other suitable material, the glassV jar merely serving to facilitate an observing of the proper functB5 Several slanting bead-likemembers or pro- `jections 10 are provided near theupper edge of the'container 9 by which the container is held to the attachment proper.

The attachment proper consists of a ilm` bracket-'portion 11 and a cap-like portion12. The cap-portion 12 is provided on its under- .side with tapped holes for the screws 13, to

hold the washers 1 4 by which the container is held to the attachment proper, the washers 75 .engaging over the bead-like members or pro- Yjection's lO'in the manner of a threaded engagement orfinterconnection. A packing Yand baffle plate 15 is disposed between the Vplate 15. Small apertures 17 are provided in the top by which air can pass into the top and thereby into the container in the direction of the arrows 18 and 19 in proportion to rthe amount of lubricant drawn from the wholedevice, so that the withdrawnlubricant is replaced by air.

Besides the comparatively small draw-tube 7, a larger tube 20-is providedto extend Vfrom the hollow of the cap-portion 12. Thisvlarger 'tube 20 is filled with a suitable medium to `bring the `lubricant from the container to a "level to be within reach of the draw-tube 'l'.

While wickmaterial isillustrated and indicated at 21, it must be understood that any 100 medium adapted to operate and function on the principle of capillary attraction, snch as a sponge, a bundle of fine tubes, or wire can be used to bring or elevate the level, or particles of the lubricant- Wit-hin reach of the draw-tube 7.

The draw-tube 7 is in this manner not in direct touch with the bulli ot the lubricant in the container and can draw only from the capillary medium such particles of theY lubricant that have been br iight within reach ot the draw-tube this medium.

Apertures 22 serve to admit air from the chamber 16 to the inside of the larger tube 2O in the direction of the arrows 23, being'at'the point from where the draw-tube receives its lubricant, this also tenes to develop a suitable dryness at this point so as to promote a proper functioning' oi the capillary medium.

The lubricant from the container 9 gradually rises in the direction of the arrows 2e by means of the capillary medium thro-ugh the tube 20, to be drawn by the tube towards the discharge in the direction of the arrow 3.

Having thus described my invention, I claim:
